Title: (EN) Wingtip device for the tip of a wing, blade of a wind generator or marine generator for reducing or even eliminating marginal swirl
Abstract: front page image
(EN)

A wing-tip device for the tip of a wing, or a blade of a wind generator, or a blade of a marine generator that makes it possible to reduce or even cancel what are known as wing-tip vortices. In the case or a wind generator, the result provides a start-up with less wind, control and energy efficiency that are highly productive throughout its use while at the same time significantly reducing the noise caused by the vortex.
